Abstract: Plastic pipe (130) has a cylindrical body having longitudinally extending concentric walls (104;106) spaced from the longitudinal axis of the pipe (130). The walls (104;106) are connected by ribs (102a;102b) extending generally radially between the walls (104;106) and longitudinally of the pipe (130). The pipe (130) is provided with a generally annular resilient axially extending sealing ring (112) entrapped at the end (100) of the pipe (130) by removing an end portion of the ribs (102a), heating and bending an end wall portion so as to entrap a portion (114) of the sealing ring (112), while permitting a second portion (116) of the ring (112) to axially project beyond the end (100) of the pipe (130) to provide impact resistance to the pipe end (100). A further embodiment involves omission of the sealing ring (112) and welding the small gap remaining after heating and bending an end wall portion to seal the pipe end (100).

Abstract: A transport vehicle (10) with a chassis (14) having an interchanging device, an interchangeable body (19) which can be positioned on the chassis (14) and removed and has at least one unit (22) which is to be driven, a coupling line (26) in particular for connecting a driving drive device (28), which is present on the vehicle side, to a power output device (24) which is to be driven and is present on the interchangeable body side, and a coupling device (40) which is present inside the coupling line (26) and has coupling elements (42, 44) in particular for coupling the vehicle-side drive device (28) to the interchangeable body-side power output device (24) is characterised by the fact that a vehicle-side coupling element (44) and an interchangeable body-side coupling element (42) are present and the drive device (28) is automatically coupled/decoupled to/from the power output device (24) when the interchangeable body (19) is positioned/removed. By means of the automatic interlocking of the coupling elements when the interchangeable body is positioned the coupling process which is still to be carried out manually in known vehicles is superfluous. The automatic coupling process increases user friendliness when changing interchangeable bodies of this kind enormously. At the same time, there is no longer any risk of injury to the operator. <IMAGE>

Filed: 1991-03-15
Abstract: A thin, efficient and uniform illuminator for large areas comprises optically clear plastic wedge (12) or a series of such plastic wedges applied to or formed integrally with a back surface of an area to be illuminated. Light is collected and concentrated from a high efficiency light source. The concentrated light is focused as an input to one or more light guides (14). The light guides may be optical fibers. The light guides or fibers are fused or mated in some other way to an edge (13) of the or each plastic wedge. The wedge shape increases the angle of the internal reflections of the edge coupled light per unit distance and intercepts more of the light as the wedge gets thinner. To further enhance the uniformity of the illuminating light, light scattering centers may be added to the surface or volume of the wedge. The number of scattering centers over the illuminating surface of the wedge or within the volume of the wedge may increase along the distance moving away from the light source.

Title: Slag processing in a rotary arc furnace.
Inventor: DROUET MICHEL G
IPC: C22B7/04
Filed: 1991-10-25
Abstract: A process is disclosed, for treating dross containing a metal such as aluminum, in order to recover this metal, In this process, the dross to be treated is introduced into a rotary or oscillating furnace, in which it is heated to a temperature above the melting point of the metal to be recovered while the furnace is rotated or oscillated to cause the metal to be recovered to separate from the dross. After the separation is completed, the metal to be recovered is removed from the furnace prior to removing the balance of the dross. In this process, the furnace that is used is a radiating arc furnace having two opposite electrodes which are preferably made of graphite, between which an electrical arc is generated and maintained in order to provide the desired heating.
